1. NANC Report Future of Numbering Working Group (FoN) FoN Co-Chairs Jim Castagna, Verizon Don Gray, Nebraska PSC Adam Newman, Telcordia Technologies May 21, 2010

2. 2 Summary of Activity Since Last Report Held three conference calls Initiated review of all the open work items Achieved consensus on a White Paper for NANCs discussion & disposition: –Toll Free Resources - Allocation, Assignment and Management May 21, 20102

3. 3 White Paper: Toll Free Resources - Allocation, Assignment and Management (FTN-005) The FoN identified issues and potential solutions raised by members of the FoN, some of which are also members of the toll free community. Current FCC Rules require toll free resources be managed and allocated much like geographic resources, e.g., first come – first served, no hoarding, no sale, barter or trading of numbers. Given some toll free numbers can be used as a mnemonic (easily remembered) to promote a business, instances in which toll free numbers are allocated outside of the Rules and Industry Guidelines have been known to occur.

4. White Paper: Toll Free Resources - Allocation, Assignment and Management (FTN-005) Potential gaps (revealed over time) in the tools available for toll free may be contributing ambiguity, and in some situations/instances, making it difficult to ensure subscribers are being treated in accordance with FCC Rules and Industry Guidelines. For example, the trail of the assignment of a number is difficult to follow, and provides opportunity for the unauthorized transfer of a number, in some cases effectively placing toll free communications with a business out-of-order. This white paper does identify issues of this nature, and potential solutions to these issues for further analysis, but it does not draw conclusions, nor does it alone substantiate a problem needs to be solved.

5. 5 White Paper: Toll Free Resources - Allocation, Assignment and Management (FTN-005) The analysis concluding with this white paper considered the significance of the issues, and examined ways of protecting Subscriber rights, including Subscriber identify, how is that entity identified, and how to ensure it maintains control of their assigned number(s). Potential solutions described are methods of introducing control mechanisms to the Toll Free assignment paradigm, which includes models for allowing direct number transfer between Subscribers. The FoN analysis considered: –Reinforcement of Subscriber rights & Resp Org obligations. –The potential use of tools to eliminate gaps, including the use of one or more property rights models, e.g., DMV. The FoN can go no further unless it obtains input from the broader Toll Free industry stakeholders. May 21, 2010 5

6. White Paper: Toll Free Resources - Allocation, Assignment and Management (FTN-005) Therefore, the FoN recommends this White Paper, or a version acceptable to the NANC, be circulated for comment to the broader Toll Free stakeholders, including the SNAC, a committee under ATIS, the SMS/800 Management Team (SMT), and various Toll Free Subscribers, for analysis, comment and input. With the support of the NANC, the FoN could then analyze the input, continue its collaboration with industry stakeholders, and evolve this White Paper into an analysis for further consideration by the NANC.

7. Next Steps Determine if the NANC wants to distribute the White Paper. Identify the points to be made in the cover letter, and who will collaborate to prepare the cover letter for NANCs approval post meeting via email.

9. Future of Numbering WG Mission To explore changes to the environment, including new and future technologies, the impact of market place and/or regulatory changes and innovations on telephone numbering. Scope: The Working Group will investigate new telephone numbering assignment approaches and future telephone number assignment requirements. The Working Group will identify common criteria and gather data to identify trends and their impact upon numbering resources. The Working Group, if necessary, will analyze opportunities to determine the feasibility and benefit of each and report its findings to the NANC. The Working Group will also analyze various topics that may be given to it from time to time by the NANC and/or FCC. May 21, 20109
